| Abstract | Long Description |
During 2002 the Department of Ecology′s Washington State Toxic Monitoring Program conducted sampling in West Medical Lake near Spokane. The study found levels of total polychlorinated biphenyls (PCBs) and dioxins in rainbow trout tissue above National Toxic Rule human health criteria. This led to listing the lake under section 303(d) of the federal Clean Water Act, for non-attainment of beneficial uses. The Clean Water Act requires states to submit to the U.S. Environmental Protection Agency a Total Maximum Daily Load (TMDL) priority list of waters that do not meet applicable criteria. To address 303(d) listings, the Department of Ecology′s Eastern Regional Office requested a TMDL assessment of West Medical Lake to (1) evaluate current levels of Total PCBs and dioxin in fish tissue, sediment, and effluent, and (2) allocate loads to sources. The TMDL assessment will include collection and analysis of six fish composites of rainbow trout and one other sport species, sediment sampling at seven sites, and four seasonal effluent samples from the West Medical Lake Wastewater Treatment Plant. |
